wick-Raises.

SPEGIFICATION forming part of Letters Patent No. 733,447, dated July14;, 1903. Application filed December 26, 1902. Serial No. 136,693. (Nomodel.)

To @ZZ whom t may concern:

Be it known that I, WILLIAM H. WILDER, a citizen of the United States,residing at Gardner,Massachusetts,have invented certain new and usefulImprovements in Wick-Baisers, of which the following is a specification.

My invention is an improvement in wickraisers, and is adapted especiallyto the raising and lowering of round wicks.

l have devised a construction which is not only very effective, butwhich permits in its manufacture the use of the cheapest grade ofmaterial instead of the most expensive kind, as heretofore foundnecessary.

Vick-raisersin use include a rack-bar moving in a guide secured to theouter periphery of the wick-tube, this rack being engaged by a pinion onthe end of a spindle which terminates in a handle. Diiculty has beenexperienced in keeping the pinion and rack in engagement, as theyfrequently get out of mesh, and it is the object of the presentinvention to overcome this and to make impossible disconnection of thepart-s.

ln the accompanying drawings, Figure 1 is an elevation of a wick-tubewith parts broken away. Fig. 2 is a vertical section. Fig. 3 is adetached view of the wick-raising bar. Fig. 4 is a detail viewshowing-.the toothed edge of the bar.

The wick-tube is of ordinary construction, consisting of an inner tube aand an outer tube l), secured thereto, forming the Wickspace betweenthem. The wick c is of the ordinary tubular type and is carried by atubular support d, having the usual flange e at the bottom. The tubularsupport,with its Wick, lits within the space between the outer and innertubes, and. the wick is raised and lowered by a device which engages thewicksupport CZ and is operated by a pinion suitably engaging the raisingand lowering devices.

frepresents a U-shaped metallic connection one arm of which extendsthrough an elongated slot g in the outer tube l), passing up into theinterior of the wick-space and inside of the wick-support d, so thatwhen the wick is in place the bottom edge of the support rests upon thebottom of the part f. The opposite arm of the sectionf is made uppreferably of a series of plates of equal width and thickness, and theseplates are toothed, as

shown at h, Fig. 4. The teeth of the outer plates are in line, but theteeth of the center plate are out of line, with the teeth of the outerplates. The series of plates are suitably secured, as by riveting, andthis arm (the outer) of the L3y passes up through a guideway t', formedon the outer periphery of the wick-tube, and here the teeth are engagedby a pinion or gear held within a suitable casing with its teethcorresponding to the teeth of the rack, the gear being made up in likemanner by several disks with the teeth out of line, so as to mesh withthe teeth of the rack. It will thus be seen that a great irnprovement issecured over the ordinary rackand-gear connection of a single thickness,as with a gear-and-rack connection such as described and shown hereinthere is a locking engagement which precludes accidental detachment. ltwill be observed that as the U- shaped member rises under the action ofthe turning of the spindle of the gear it moves upward the wick throughits ring-support, as the parts of the U inclose the said support. Itwill also be seen that as the inner limbfof the U-shaped member extendsupwardly between the tubular wick-support (l and the inner wall of thewick-tube it serves to prevent binding of the parts and makes theup-anddown movement a free one. In order, however, to move the wickdownwardlyin the reverse action of the handle, l provide the plate f ofthe toothed series with an inwardlyturned projection 7c, and thisengages the flange e ofthe tubular wick-support and moves it downwardly.the wick with its support bodily, the flange e of the support d isreleased from the projection 7c of the plate f by reason of the factthat the plate bears upon the wall forming the upper edge of theelongated slot, (see k, Fig. 1,) and this forces the plate f', carryingthe projection 7c, outwardly, releasing it from engagement with thewick-support.

l. A wick-raiser including a raising and lowering connection comprisinga U-shaped member having a rack with teethy out of line with each otherand a gear having teeth corresponding thereto, substantially asdescribed.

2. A wick-raiser including a toothed bar When it is desired to remove Amade up or" a series of plates with teeth in staggered relation and agear having teeth corresponding thereto, and adapted to engagetherewith, substantially as described.

3. A wick-raiser including a U-shaped element havinga toothed edge madeup of a series of toothed plates with a part of the teeth out of line, agear correspondingly toothed and engaging the toothed bar, means forengaging the wick-support so as to raise and lower the same in themovement of the raising and lowering element, substantially asdescribed.

4. A wick-raiser comprising a raising element consisting of a toothedbar made up of a series of plates with the teeth of one plate out ofline with the teeth of the other plates, and a gear correspondinglytoothed, and engaging therewith.

5. In combination with a toothed member made up of plates with teeth instaggered relation, a gear having teeth corresponding thereto andadapted to engage therewith.

6. A wick-raiser including a U-shaped element inclosingawick-support,the outer member having rows of teeth out of line and agear toothed to correspond thereto, substantially as described.

'7. In combination, a member made np of a series of plates with teeth instaggered relation and a corresponding member engaging therewith,substantially as described.

8. A wick-raiser including a U-shaped element inc-losing a wick-support,the outer member having rows of teeth with a gear toothed to correspondthereto, the inner member being interposed between the wick-support andthewall of the tube,substantiallyas described.

In testimony whereof I affix my signature in presence of two witnesses.

VILLIAM I-I. VILDER.
